DOUBLE--ROVV` CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 611,321, dated September 27, 1898.

Application filed December 20, 1897. Serial No. 662,653. (No model-l l To all whom it may concern.-

Be it known that I, PHILIP JARvIs, a citizen of the United States, residing at Cedar Rapids, in the county of Boone and State of Nebraska, have invented a new and useful Double-Row Cultivator, of which the following is a speciiication.

My invention relates to improvements in double-row cultvators designed to be drawn by three horses and operated by one attendant for cultivating two rows of corn at one operation; and among other things the objects that I have in view are to provide an implement in which the draft is kept low down substantially in line with the shovelbeams; to provide for the horizontal adjusting of the shovel-beams toward or from each other and accommodate the shovels to the spaces between the rows; to enable the beams to be suspended in raised positions out of the way for convenient carriage to or from a field or in turning at the ends of rows; to enable either of the beams to be adjusted in a vertical direction independently of every other beain of the series and thereby enable said beams to be cleared from accumulations of trash; to insure the lateral adjustment of the shovel-beams simultaneously, and to simplify the construction and reduce the number of parts, as well as to promote the strength and durability thereof.

With these ends in view the invention consists in the novel combination of elements and in the construction and arrangement of parts, which will be hereinafter fully described and claimed.

To enable others to understand my invention, I have illustrated the same in the accompanying drawings, forming part of this specication, and in which- Figure l is a perspective view of a cultivator constructed in accordance with my invention. Fig. 2 is a longitudinal sectional view thereof. Fig. 3 is a detail perspective view, on an enlarged scale, of the couplingbar between the shovel-beams to insure the simultaneous movement of all of the beams. Fig. 4 is a detail perspective view of one of the side stirrups for use in connection with a single shovel-beam, and Fig. 5 is a detail perspective view of the central stirru p adapted to sustain a pair of shovel-beams.

Like numerals of reference denote like and corresponding parts in each of the figures of the drawings.

Referring by numerals to the drawings, 1 designates the main axle of the machine, which, as is usual in this art, is equipped at its ends with the axle-spindles 2, on which are loosely mounted the carrying-wheels 3. To the main axle, at points on opposite sides of the longitudinal center of the machine, are fastened the tongues 4 by means of the bolts 5, and these tongues are braced by the struts 6, having their ends rigidly bolted to the axle and to the tongues. The tongues are thus united to the axle in a manner to have the joints reinforced or strengthened, and the rear ends of the tongues are extended beyond the axle to afford the means for the attachment of the {suspending-standards by which the shovel-beams may be held in their raised positions, as Will-hereinafter appear.

Depending from the lower side of the main axle l, near or adjacent to the carryingwheels 3 thereon, are the side stirrups 7 8, one

of which isV shown bythe detailed view Fig. 4 of the drawings. Each stirrup consists of a flat bar or strap of metal bent into the shape shown by Fig. 4, and the ends ofthe bar or strap are fastened securely to the under side of the main axle.v The horizontal part of the stirrup affords a rest for the front end of a shovel-beam and above this horizontal len gth of the stirrup is arranged a cross-plate 9, which is parallel to the stirrup and has its ends iianged to enable the same to be bolted to the vertical lengths of the stirrup. The front end of the shovel-beam is iitted snugly between the stirrup and its cross-plate 9, and in said stirrup and cross-plate is provided a series of verticallyalined apertures 16, through any pair of which may be passed an attaching-bolt 17 to confine the shovel-beam pivotally within the stirrup. The shovelbeam maybe adjusted laterally in a horizontal direction within certain limits within the stirrup by removing the pivotal bolt 17 and fitting it in either pair of apertures in the stirrup and its cross-plate, and this pivotal l is equipped with a cross-plate bolt and the shovel-beam are so attached to the stirru p that the shovel-beam may be capable of alimited adjustment in a horizontal and vertical direction, as may be desired in the practical operation of the implement.

A single central stirrup l is provided on the main axle between the side stirrups 7 8, and said single stirrup is designed to afford asupport for the front ends of a pair of shovelbeams, whereby the central stirrup is common to two of the shovel-beams of the implement. This central stirrup is illustrated by Fig 5 of the drawings, and it consists of a single bar or strap of metal bent to provide the horizontal length and vertical branches, the latter being securedV rigidly to the under side of the main axle 1. This central stirrup 10, flanged at its ends and bolted or otherwise fastened to the vertical branches of the stirrup, and said stirrup and its cross-plate are provided with vertically-alined pairs of apertures 16 to receive the adj listing-bolts 17, by which the middle shovel-beams are attached pivotally and adjustably to the stirrup.

It will be observed from the foregoing descri tion taken in connection with Figs. 4

and 5 of the drawings, that the central stirrup is similar in all substantial respects to the side stirrups; but this central stirrup is somewhat wider or longer than either of the side stirrups to enable it to be used in connection with the pair of central shovel-beams.

The side stirru ps are braced by the employment of rods or struts 26, which are fastened in a suitable way to the under side of each stirrup and extend in a diagonal direction up to the tongues 4, to which they are bolted or otherwise rigidly fastened, and these braces or rods 26 serve to strengthen the stirrups against the strain of the shovel-beams when the implement is in service, so that the parts are not liable to break and get out of order.

The side beams of the implement are indicated at 11 and 12 in Fig. l of the drawings, while the central beams are designated by the numerals 13 and 14.

As'will be understood by reference to the foregoing description, the side beams 11 and 12 are attached individually to the side stirrups 7 8, while the pair of central beams 13 14 are attached separately to the single central stirrup 10. Each shovel-beam may be of the usual or any preferred construction, and it is provided with an ordinary stock and shovel. As no novelty is claimed for the construction of the beams, the stocks thereof, or the shovels thereon, I have not deemed it necessary to more fully and at large describe and illustrate the construction and arrangement of these parts.

Each shovel-beam is provided with a handle 18, by means of which the beam may be adjusted horizontally or vertically, as may be found necessary in the practical service of the machine.

To insure the simultaneous adjustment of all the shovel-beams and insure their proper operative relation to the rows under cultivation, I provide a sectional coupling-bar which is common to all of the series of shovel-beams in the implement. This coupling-bar is represented by the detailed view, Fig. 3, of the drawings, by reference to which it will be seen that the coupling-bar consists of two members or sections 19 20, arranged to overlap each other at their meeting ends and provided with vertical apertures adapted to coincide witli each other for the reception of the fastening-bolts 22, whereby the sectional coupling-bar may be extended longitudinally to adapt the same to be used in connection with the 'shovel-beams when the latter are adjusted horizontally or laterally in their stirrups on the main axle. The coupling-bar is provided with the arches or yokes 21, and it is further provided with apertures 22a, adapted to receive bolts 22b for attaching the coupling-bar to the beams forming the series of shovel-beams of the implement, each shovelfbeam bolted individually to the coupling-bar, as represented by Fig. 1.

From the foregoing description, taken in connection with the drawings, it will be seen that the shovel-beams are pivoted to their stirrups for horizontal adjustment, and by employing an extensible coupling-bar I am able to provide means which serve to operatively connect togetherall of the shovel-beams and permit of said horizontal adjustment in the stirrups on the main axle.

To the extended rear ends of the tongues 4 are rigidly attached the suspending craneshaped arms 23. These arms have horizontal feet 25, which are applied to the tongues and bolted secu rely thereto, and said arms extend upwardly from the tongues and terminate in the hooks 24, with which are adapted to engage the yokes or arches 2l of the couplingbar, whereby the coupling-bar and the arms 23 serve as the means for suspending the shovel-beams in their raised positions, as indicated substantially by Fig. 1 of the drawings.

It will be evident that the operator may readily lift the shovel-beams and the coupling-bar to permit the yokes or arches of said coupling-bar to engage with the hooks of the suspending-arms, thus arranging the shovelbeams out of operative position and enabling the same to be carried in a convenient manner to or from the field; but when it is desired to bring the shovel-beams into service it is only necessary for the operator to detach the coupling-bar from the hook-shaped suspending-bars and lower the shovels to their horizontal positions, substantially as indicated by Fig. 2 of the drawings.

The shovel-beams are attached to their stirrups by vertical and horizontal pivots, as represented by Fig. 2, and this attachment permits of the lateral swinging motion of the IOO IIO

shovel-beams in a horizontal direction to enable the shovels to be adjusted to the rows of corn which it is desired to cultivate and also provides for the raising and lowering adjustment of said shovel-beams to enable the same to be cleared from accumulations of trash.

On the tongue-bars -l of the implement are pivotally attached the doubletrees 27 28. In connection with these doubletrees I use aseries of three whiffletrees 35, one of which occupies a horizontal position below the adjacent inner ends of the pair of doubletrees, while the other two singletrees are arranged below the outer ends of said doubletrees. These singletrees are carried by the vertical draft-bars 29, which are operatively connected with the doubletrees and with the stirrups to which the shovel-beams are attached,\vhe1'eby the draft is kept low down with relation to the shovel-beams.

The outside vertically-disposed draft-bars 29 are each loosely connected at its upper end to the outer extremity of one of the doubletrees by a loose connection, as indicated by 3l, and the lower end of each draft-bar 29 is attached to a link 30, which extends in a horizontal v direction rearwardly to one of the stirrups,

to which stirrup the rear end of the link 30 is attached by means of a bolt 30a. The vertical draft-bar for the middle whiffletree carries a pulley and bracket 32 at or near the upper end thereof, and in this pulley-bracket is loosely j ournaled a pulley 33, around which passes a chain or other pliable connection 34, having its ends fastened to the inner adjacent ends of the doubletrees 27 28.

To the front ends of the tongne-bars 4 of the implement are attached the neck-yokes These neck-yokes may be of the usual or any preferred construction and they are attached to the tongue-bars in any suitable manner.

It is thought that the operation and the advantages of my improved cultivator will be readily understood from the foregoing description, taken in connection with the drawings.

It is evident that changes in the form and proportion of parts and in the details of construction may be made without departing fromthe spirit or sacrificing the advantages of the invention.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is- 4 1. In a cultivator, the combination with a carrying-axle, of the side stirrups rigidly fastened to said axle and provided with the cross-plates,` the side beams pivoted individrups, the side beams pivoted individually to l the side stirrups and adjustable horizontally therein toward or from the middle beams, and a pair of middle beams pivoted in said central stirrup which is common to both beams and adjustable horizontally therein toward or from the side beams and each other, substantially'as and for the purposes described.

3. In a cultivator, the combination with a wheeled frame, and depending stirrups, of the shovel-beams hung within the stirrups for adjustment horizontally therein and adapted to be lifted on their pivotal connections with the stirrups, an extensible coupling-bar having its members unitedrigidly to pairs of the shovel-beams and adj ustably fastened together at a point between adjacent pairs of said beams, and crane-like arms mounted on the frame for engagement with the couplingbar to suspend the shovelbeams in their raised positions, substantially as described.

4. In a cultivator, the combination with a wheeled axle, the draft -tongues, andV the shovel-beams, of the side stirrups in which the side beams are individually hung, the center stirrups supporting the pair of middle beams,the doubletrees pivoted on the tongues, the side depending draft-bars pivotally connected to the ends of the doubletrees and linked to the side stirrups, a central draftbar linked to the central stirrup, a guideroller carried by thecentral draft-bar, and a chain passing around the roller and attached to the adjacent ends of the doubletrees, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.`

PHILIP JARVIS.
